Description
上述の課題を解決するための本発明は、エンドレスベルトと、第一の面と、前記第一の面と反対側の第二の面と、を有する板状のヒータであって、前記第一の面が前記エンドレスベルトの内面に接触し、基板と、前記基板上に設けられた発熱抵抗体と、を有するヒータと、
前記ヒータの前記第二の面に接触し、前記ヒータの前記第二の面に平行である方向の熱伝導率が前記第二の面に垂直である方向の熱伝導率より高い熱伝導異方性シートと、前記熱伝導異方性シートを介して前記ヒータを支持する支持部材と、を有し、前記エンドレスベルトを介した前記ヒータの熱で記録材に形成されたトナー像を加熱する像加熱装置において、前記熱伝導異方性シートは複数枚重ねられてた状態で前記ヒータと前記支持部材の間に挟まれていることを特徴とする。
The present invention for solving the above-mentioned problems is a plate-like heater having an endless belt, a first surface, and a second surface opposite to the first surface, A surface of which is in contact with the inner surface of the endless belt, and a heater having a substrate and a heating resistor provided on the substrate;
A thermal conductivity anisotropic which is in contact with the second surface of the heater and whose thermal conductivity in a direction parallel to the second surface of the heater is higher than a thermal conductivity in a direction perpendicular to the second surface image heating and sex sheet, a support member for supporting the heater through the heat conducting anisotropic sheet has the toner image formed on a recording material by heat of the heater through the endless belt In the heating apparatus, a plurality of the thermally conductive anisotropic sheets are sandwiched between the heater and the support member in a state of being stacked .
